Removing an instance group from a placement group

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

1. See the description of the CLI command for updating a group:

   yc compute instance-group update --help
   

2. Get a list of instance groups in the default folder:

   yc compute instance-group list
   

   Result:

   yc compute instance-group list
   +----------------------+-----------------------+------+
   |          ID          |         NAME          | SIZE |
   +----------------------+-----------------------+------+
   | amc65sbgfqeq******** | first-instance-group  |    2 |
   +----------------------+-----------------------+------+
   

3. Select ID of the instance group in question.

4. Delete the placement_policy section from the YAML file you used to create the group, e.g., specification.yaml. If this YAML file is missing, get info on the instance group and create a new file. For more information, see Creating a fixed-size instance group.

5. Update the instance group in the default folder:

   yc compute instance-group update --id <instance_group_ID> --file specification.yaml
   

Instance Groups will initiate removing the instance group from the placement group.
